Definitions

  • the invention relates to a device for injecting plastic molded parts, in particular a nozzle device which can be inserted into a mold, wherein the nozzle device comprises a first and a second nozzle body and a connecting element for connecting the nozzle body, wherein the nozzle body and the connecting element each have a feed line for molten material in that the molten material is conveyable from the second nozzle body via the connecting element into the first nozzle body, wherein the first nozzle body has at least one feed channel for injecting the molten material into a mold cavity of the mold, and wherein the connecting element is connected to the nozzle bodies Relative movement of the nozzle body in the direction of a longitudinal axis of the nozzle body is made possible. Furthermore, the invention relates to a tool assembly with a mold plate and a nozzle device.
  • nozzle devices or tool assemblies are regularly used when a tool assembly, due to their structure, relatively expensive can be mounted or dismounted.
  • the nozzle device is a multi-tip nozzle in which a plurality of mold cavities are arranged laterally next to the nozzle device in a molding tool.
  • a central supply line in a nozzle body branches in a star shape into injection channels for lateral injection molding of the mold cavities, wherein nozzle tips are arranged in the injection channels, which project beyond the nozzle body and engage in the mold.
  • the nozzle body therefore can not be readily removed from the mold.
  • the mold must necessarily be designed in several parts, or the nozzle body must be designed so that it allows independent of the mold assembly or disassembly of the nozzle tips.
  • the mold does not have to be dismantled if, for example, it is to be removed for cleaning purposes by a mounting plate of the tool arrangement holding the nozzle device.
  • the known nozzle devices therefore have a first and a second nozzle body, which are connected by means of a connecting element so that they can be pushed into each other in the manner of a pipe coupling or pulled apart.
  • a flexible annular seal is provided in a connecting region between the connecting element and the first nozzle body, which is arranged on an end side of the connecting element and sealingly abuts against an opposite end side of the first nozzle body.
  • the sealing element bridges an axial sealing gap, the longitudinal mobility given in the context of the flexibility of the sealing element the two nozzle body allows compensation of the linear expansion.
  • the disadvantage here is that only minor length expansions can be compensated, since the tightness of the connection depends on the size of the sealing gap and the sealing element arranged therein. Also, care must always be taken during a mounting on a correct fit of the sealing element or possible damage to the same. To exclude any leaks, it is therefore advisable to renew the sealing element during assembly. Incidentally, it requires in the above-described nozzle device disassembly or assembly of the mold, since an exchange of nozzle tips is not provided regardless of the mold.
  • the present invention is therefore based on the object to propose a nozzle device which allows a particularly simple assembly and disassembly and can compensate for comparatively large changes in length due to the effect of temperature.
  • the inventive device for injection molding of plastic moldings in particular a nozzle device which can be inserted into a mold, comprises a first and second nozzle body and a connecting element for connecting the nozzle body, the nozzle body and the connecting element each having a supply line for molten material, such that the molten material from the second nozzle body via the connecting element in the first nozzle body is conveyed, wherein the first nozzle body has at least one feed channel for injecting the melt material into a mold cavity of the mold, and wherein the connecting element is connected to the nozzle bodies, that a relative movement of the nozzle body is made possible in the direction of a longitudinal axis of the nozzle body, wherein a connection region between a nozzle body and the connecting element is formed so that the connecting region is self-sealing.
  • connection area can be dispensed with the use of a sealing element with the known from the prior art disadvantages.
  • length changes are basically limited only by a length of the connection area.
  • the connecting element is formed in one piece, the connecting element can be produced in a particularly simple and cost-effective manner. Also, such a number of components of the nozzle device can be reduced, which further simplifies assembly and disassembly.
  • the connecting element can be firmly connected to the second nozzle body.
  • the connecting element can be firmly screwed to the second nozzle body, so that no movable seal has to be formed here for this connection.
  • the connecting element can be firmly connected to the first nozzle body. This results in the advantage that a longitudinal extension of the connecting element is not in the region of the first nozzle body takes place, but on the second nozzle body. A size of the first nozzle body can be reduced, since no self-sealing connection area must be formed here. Because the self-sealing connection region is then formed in the second nozzle body, the self-sealing connection region is exposed to less high temperature stresses, since the connection region can be arranged at a distance from the heaters of the nozzle device.
  • the connecting element may be formed by a nozzle body. That is, it can be dispensed with a separate design of a connecting element, since then both nozzle body can be directly connected to each other, such that the connection area between the two nozzle bodies is formed. As a result, the structure of the nozzle device can be further simplified.
  • connection region can easily be made self-sealing if a radial outer surface of the connecting element and a radial inner surface of one of the two nozzle bodies form a seal. That is, the connecting element and the nozzle body in question are joined to one another in such a way that between the radial surfaces an annular gap is formed in the manner of a fit, which allows a movement in a longitudinal direction and nevertheless ensures a sufficient sealing of the connecting region.
  • the connecting element can form a radial sealing wall of the supply line, which can exert a sealing force on the radially inner surface of the nozzle body.
  • an end or a portion of the connecting element may be formed so that a thin wall in the manner of a membrane between the supply line of a nozzle body and a peripheral diameter of the connecting element is formed.
  • the Extend peripheral diameter such that a seal between the radial inner surface and an inner diameter of the nozzle member and the peripheral diameter of the connecting element is formed.
  • the self-sealing connection region can thus be adapted in terms of its sealing effect to the pressure conditions prevailing in the supply lines.
  • a prerequisite is that at least in a portion of the connection region, the supply line of the connecting element is relatively coaxial with the supply line of the nozzle body.
  • the feed line of the connecting element in the connecting element branches off into a feed channel of the first nozzle body extending transversely to the feed line. Consequently, the connecting portion may be formed so that at least one opening is formed on a peripheral surface of the connecting member, which allows a connection of the supply line of the connecting element with the supply channel of the nozzle body.
  • the connection region is also self-sealing in this case and may have a plurality of radial sealing surfaces or sealing surface pairings.
  • the first nozzle body has a positioning device for the stationary positioning of the first nozzle body in a molding plate of the molding tool.
  • the positioning device can be designed such that the first nozzle body is fixed in a form-fitting and / or force-locking manner in the mold plate such that nozzle tips of the nozzle body can be aligned in the desired position relative to injection channels formed in the mold plate.
  • the first nozzle body can therefore be fixed independently of the second nozzle body, which is positioned or fixed relative to a receiving plate in which it.
  • a collar of the first nozzle body can form the positioning device, wherein the collar, the first nozzle body can position in the axial and / or radial direction in the mold plate.
  • the federal government can be formed at an upper end or at a lower end of the first nozzle body coaxial with the longitudinal axis thereof.
  • the federal government may be polygonal and engage in a matching trained receiving shoulder of the mold plate.
  • the collar may be round, square or polygonal, wherein the receiving portion of the mold plate then preferably has a matching shape. Consequently, the first nozzle body can form any radial shape regardless of the collar and have any desired arrangement of nozzle tips.
  • a pin may be provided on the collar, which engage in a mounting recess of the mold plate and can position the first nozzle body in a radial direction.
  • the mounting recess may be formed, for example in the form of a groove in the mold plate, which extends in the direction of the longitudinal axis of the first nozzle body.
  • the pin or alternatively a screw or nose of the collar can then be inserted into the groove and allow a radial positioning of the first nozzle body.
  • a mounting recess may be provided in the manner of a bore, in which a frontally attached to the collar pin, a screw or a nose is used.
  • the first nozzle body is designed such that it can be inserted from a front side of the mold plate into it.
  • the mold plate For disassembly of the first nozzle body then the mold plate must not be removed from the receiving plate.
  • the first nozzle body can thus be removed directly from the front side of the mold plate, which requires due to the formation of the connection area only a withdrawal of the first nozzle body from the connecting element or from the second nozzle body, without additional steps would be necessary to solve the connection area.
  • the positioning device comprises a fastening screw, which can be inserted from the front side of the mold plate in the first nozzle body or from a back of the mold plate in the mold plate and can position the first nozzle body in the axial direction. This ensures a secure fit of the first nozzle body in the mounting recess of the mold plate and prevents accidental falling out of the first nozzle body from the mounting recess during disassembly of the mold.
  • the first nozzle body can form at a lower end a nozzle crown for injection molding of laterally arranged next to the first nozzle body mold cavities.
  • the nozzle device can be designed as a multi-tip nozzle, wherein preferably the nozzle crown can be designed so that nozzle tips of the multi-tip nozzle can be removed from the front side of the mold plate from the nozzle crown or inserted into it.
  • the first nozzle body can thus remain in the mold plate or it is no longer necessary to form the injection channels forming mold plate of the mold for a mounting or dismounting of the first nozzle body in several parts.
  • an extension portion is formed between the nozzle crown and an upper end of the first nozzle body.
  • the extension portion may be formed, for example, in the manner of an annular groove between the collar at the upper end of the first nozzle body and the nozzle crown with the nozzle tips at the lower end of the first nozzle body.
  • a length of the extension portion can then be selected depending on the thickness of the mold plate.
  • the extension section can be sleeve-shaped, such that a heating device of the second nozzle body can be arranged at least partially in the first nozzle body. That is, the extension portion bridges only a distance from the collar to the nozzle crown without the extension portion itself forms a supply line.
  • the extension section covers in this area the second nozzle body, the heating device of which extends into the extension section, which ensures an advantageous temperature control of the supply line.
  • a recess may be formed in the first nozzle body, which is arranged between a heating device and the feed channel of the first nozzle body such that heat energy of the heating device is directed in the direction of an injection channel of the first nozzle body.
  • the recess may be formed in the form of a radial annular gap, which prevents an immediate transition of heat energy of the heater to an upper portion of the feed channel due to its insulating effect. That is, the heat energy is transferred to the first nozzle body and is guided due to the annular gap in a lower region of the feed channel and a portion of the injection channel of the first nozzle body. For example, heat losses via sealing rings of the first nozzle body, which are in connection with the mold, can be compensated.
  • an optimized temperature profile for the first nozzle body can be achieved by the shape of the recess, which acts on the melt material in the feed channel and in the injection channel in the desired manner with thermal energy or tempered.
